BOTTLE-STOPPER OF CELLULOID OR ANALOGOUS MATERIAL.

SPECIFICATION forming part of Letters Patent No. 255,655, dated March 23, 1882.

Application tiled December 9, 1881. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN S. NEw'roN,a citizen ofthe United States o'.A1'iierica,resid ing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements iu Bottle-Stoppers of Celluloid or Analogous Material; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,whichform a part of this specification.

This invention relates to the production, as a new article of manufacture, of dischargingtubes, through which the contents of a bottle are to be delivered.

In the drawings, Figures 1, 2, 3, 4, and5 are vertical sections of bottle-Stoppers the discharge-tubes of which are made in accordance with my invention.

In Figs. l and `2, D is a discharging-tube; D', a flange covering the cork-tube or bottleneck; E, a hood, screw-threaded to engage with the screw-threaded upper end of the discharge tube, and constructed with the central valv'e, e, and discharge-ports e.

In Fig. 3, F is an internally-threaded tube section or socket, supported centrally 4in ange D', and provided at the bottom'with ports g anda central conical projection, g. H is a discharging-tube, screw-threaded externallyv to engage with the throat of the tube-section F, and havinga dischargeopening, h, through out its entire length, which is closed when .screwed down against the part g', as will be readily understood without a more detailed description. i

In Fig. 4 the discharge-tube D does not pro` ject below the flange D', but is screwthread ed externally, as are the corresponding tubes in Figs. l and 2. I is a hood, screw-threaded internally to engage with and close the dischargetube, the upper end of which the hood ts closely when screwed down.

In Fig. 5 the discharge-tube Dis constructed with an external enlargement, d, near its 4upper end, which may be of the form shown, or may consist merely of a circumferential rib or bead; but I prefer that shown. J J is an elastic hood ofan internal diameter slightly less than the external diameter ofthe discharge-` tube at its upper end, so that as the hood is forced over the enlarged part fl itis expanded.

Therefore the hood will be held firmly in place i upon the discharge-tube by reason of its contractile power.

Celluloid possesses many advantages as a material of which to manufacture bottle-stoppers, an important one heilig that it is not subject to discoloration by contact with vul canized rubber, as is the case with metals ordinarily employed forsuch articles. Hence the stopper will not be tarnished by contact with the hood, which, by preference, is made of vulcanized rubber. Again, the strength and rigidity of celluloid make it-specially desirable as a material from which to manufacture the discharging-tubes of bottle-Stoppers of the various forms described above, from the fact that it will not readily yield to pressure. Hence there is little liability in ordinary use of the parts becoming bent or collapsed so as to preveut the screw-threaded parts from operating properly'. Noris Celluloid discolored or corroded by the action of liquids with which the discharge-tube of a bottle-stopper is liable to be brought in contact-such as vinegar, acids,

table-sauce, or other condiments, or by per-
